Hi Madhumitha,
Firstly, you need to allow anonymous users to be able to access your app. You can set it in the App Security page.
Then you would need to add an anonymous user role in the ‘User roles’ tab in the App Security settings. It will prompt you whether you want to create anonymous user roles for your other current modules too. You can configure that based on what you need.
You can then set your pages to allow anonymous user to view it
